Abstract (en)
[origin: EP0167957A2] Acid compounds can be isolated in the free form from their aqueous solutions, when the acid solutions are contacted with weakly basic adsorber resins, the loaded resins are, as appropriate, washed with water and/or an organic solvent and the adsorbed acid compounds are desorbed with water and/or steam. Weakly basic ion exchangers having tertiary amino groups are preferred as the adsorber resins.
